ATLANTA — A professional wrestling event at Atlanta’s Philips Arena is one of several possible targets for Sunday attacks by Islamic State terrorists, an online post purpotedly tied to the cyberactivist group Anonymous claimed Saturday.

Federal Bureau of Investigation officials said the agency was aware of the “alleged threat” and taking it “seriously” — but added that there was no “specific or credible information of an attack at this time.”

“We have, however, made the proper notifications as we continue to work closely with our law enforcement and private sector partners to keep our community safe,” J. Britt Johnson, special agent in charge of the FBI’s Atlanta field office, said in a statement emailed to The Atlanta Journal-Constitution.

In the wake of the Nov. 13 terrorist attacks that left 129 dead in Paris, Anonymous renewed its cyber offensive against the Islamic State, claiming to have taken down thousands of social media accounts associated with the terrorist group. On Saturday, the hackers reportedly posted online that three events in Paris were “at risk” of attack Sunday, as well as others in Rome, Indonesia, Italy, Lebanon — and Atlanta.

The post mentions by name the WWE Survivor Series, a professional wrestling event scheduled for 8 p.m. Sunday at Philips Arena.

“There will be big events worldwide on the 22nd, go at your own risk,” the post said.
